bugref:8677: Additions/Graphics/Wayland: Fedora 25 issues: fix sending virtual screen offset hints (recent guests only). If the hints are not for disjoint screen areas (GNOME Shell requires this), replace them with default ones. Having valid hints lets us know the virtual screen layout inside GNOME Shell/Wayland unless the user has manually changed it inside the guest, and we need this information to get the (absolute) pointer input mapping right. The code also detects and handles separately the special cases of the fbdev console being active and X.Org (a single large framebuffer for all screens in video memory).
